Two things come to mind with this. Explosions will kill the lights and fill the area with smoke. Hence you have darkness and an environment filled with choking smoke to deal with.

That's why I carry a SureFire E2e and N95 Particulate Filters everyday. The SureFire is on my person. The filters are in my shoulder bag. I also have two bandannas on my person.

Should I survive the initial explosion and be ambulatory, I would hopefully be able to breathe and see well enough to escape.
